.htgroup

The format of the group file is straightforward, one line per group, with the line containing the group name, followed by a colon, followed by the users in the group. Users are separated by commas.

In other words, an .htgroup file can look like this:

   all:frotz,gnusto
   admins:frotz   
with one line per group.
